Embedded Transformers

Embedded transformers

Some types of transformers can be etched from standard pcb materials as part of regular multilayers without special process. The design problem is number of layers required and how to match this with other pcb requirements that may require very few layers. The alternative is to have dedicated “transformer pcbs” made with multilayer technology. The produced planar transformers can then be assembled as any other (SMT) components, for instance for DC/DC (isolated) or/and distributed power conversions.
